| Abstract: |
| Based on the calculation for different types of oasis eco-environmental water requirements in middle reaches of Shulehe River, estimated the water requirements scale of oasis eco-environment. The calculated results indicated that the maximal, minimal and the most suitable eco-environmental water requirements were 7.22×108 m3, 5.58×108 m3 and 7.09×108 m3 respectively, which was occupied 46.4%, 35.7% and 45.3% of the gross amount of water esources(15.65×108 m3）in middle reaches of Shulehe River respectively. Under the conditions without consider and consider the water requirements for sand transportation, the eco-environmental water requirement in Shulehe River was 2.49×108 m3 and 2.62×108 m3 respectively. However, put forward the management countermeasures for water resources as regulation and management of ecological water requirements base on rational allocaion of water resources, construction of water-saving society, information management technology, laws and regulations and policy system. |
